Unusual Growth Characteristics of a Methionine-Cyano-B(12) Auxotroph of Escherichia coli

Escherichia coli K-12, strain AB1172, substrain 2276, a methionine(−)-cyano-B(12)(−) auxotroph grew poorly when placed in a medium containing optimal levels of cyano-B(12) and suboptimal amounts of l-methionine. A marked depression of N(5,10)-methylene-H(4)-folate reductase was observed in the inhib...
